On-farm composting in an area no more than 5,000 square feet using covered windrowing, in-vessel systems, and/or aerated static pile (ASP) technology, when used to process offsite waste organic Category I, Category II, or Category III feedstocks in containers designed to prohibit vector attraction and prevent nuisance odor generation.  “On-farm” sites would be defined as farming operations as the primary land use on the property. Feedstock piles may not be higher than 9 feet and all other piles are limited to a height of 12 feet. When determining the area used in support of composting, include areas used for feedstock receiving and preparation (such as mixing, shredding, water addition), active composting, curing, and storage (including compost, equipment, and waste). The areas do not need to be contiguous and spaces not used for any of the activities listed above may be omitted, including empty fields and roads. For an area greater than 5,000 square feet, approval from the department will be required prior to composting.
